Wow, that was exciting and awesome! I needed a pair of new clothes and thought I'd try something new, I'd already had a blowjob and threesome in a changing room, but I hadn't done it all by myself in there yet! There was hardly anyone there apart from the shop assistant in the changing rooms, which made it even more conspicuous for me. Anyway, I went into the changing room, tried on a tight top and off I went. It was really quite cool to play around with myself while everything around me was completely normal. At one point, however, I thought the shop assistant was going to ask if everything was OK. Unfortunately, there was a very small slit through which you could have looked into the changing room. But all went well  I went on shopping relaxed!!!
